Celestia has made a mistake, however only one knows what this mistake is, because it hasn't happened yet. One thing is for sure though, whatever it is will bring about destruction one way or another. The mane six will need the help of a timelord and another unknown entity to overcome the odds, but will they get that help? Will they even trust it? If not everything will collapse.

Tags are prone to change or be added depending on what happens as I'm not entirely sure what I'm going to do next. I know three or four key points to happen. Besides that I know just about as much as you.
